To all 'whom t may concern:

.Be it known that I, JOHN J. PA'rann, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Tires, of which the following is a spcciticatien'.

My invention while applicable to wheel tires generally is especially adapted for use in connection with vehicles designed for heavy traction, such as automobilcf; and wagons employed in coinrnerciai transpor tation, provided with wheels having relar tively broad tires and solid elastic resilient treads.

The main object of the invention is to ai ford simple but effective mea s l tire may be quickly and conveniently appl `to or removed from the wheel telly; and i' and arrangement of parts herein descrit ,f and claimed,-a distinctive feature being the use, in conjunction with a. Wheel having a permanent peripheral felly band, and with a detachable tire rim, of annular we" flange side plates adapted to detachahlj. cure said tire rim to the said eliy as -tei after set forth.

n the accoinlnxnyipg drawings, Figui is a side elevation of a portion. ci. embodying my invention; Fig. 2, is a or face View of a portion of the tire, shown for convenience of illustration as extended in a horizontal plane; Fig. 3, is a transversesection taken upon plane of line 3-*3 Fig. Q; Fig. 4, is a longitudinal sectional view taken upon planes of line 4 4 Fig. 2, the curvature of the rim &c. being shown as in Fig. l; Fig. 5, is a face View of a portion of the tire rim. Without the treads, cap plates, 5to; Fig. 6, is I7a View of a portion of the underside of the tire rim; Fig. 7, is a detail View of the inner side of a portion of one of the annular Wedge-flange side plates; Fig. 8, a section upon plane of line 8-8 Fig. 7; and Fig. 9, a transverse section of the tire rim taken upon plane of line 9-.9 Fig. 5.

The felly F, of the wheel is provided with the usual permanent peripheral metallic band f. Over this fits my demountable tire rim R, on the face of which are positioned and secured elastic resilient tread sections T, T, preferably arranged diagonally as in Letters Patent No. 998,980, issued to me July 25th, 1911, although this is not essential, the gist pf my present invention relatin this connection it is to i ,ribs am, if, on the tace. e* are promoted mainly ing to the method of, and means for, de,u

tacliably ,securing the tread rim R, to the itchy. To' this end the under side of 'the tire rim f, is formed with the inclined annular marginal bearing surfaces 1, 1', and with the recesses r', r', the latter to accommodate the nuts, n, n, which secure the bolts b, by which the cap plates c, c, are held in positionf-seid cap plates c, c, 'n used as heretofore tdhear upon the .ila ses t, t, of the tread sections T, T, and hina the treads 1n position upon the face et' the tire rimy R. noted that the le tire rim R, the pt irpose of pocorrectly and accuan? Bini, although they incidensitioning the treads i rat-ely on s cement, act- Y. c i c, c, and baits 5i, I?, do also the. side fie-.rines 2, of the tir1 L) a v By the f5 visten nit the recesses fr', 1", on the under side et the e rim lit, and the ds "lll, "if, directly and solely rende-red indethe holts b, t), "rile the tire tit, applicable and removable from, the without the need ci. disturbing any of i s component parts. The depth of marginal inclined bearingl surfaces 7i, r, and of the ribs r2, r2, whlch constitute the side Walls of the recesses r, r", is identical, so as to bear evenly and uniformly on the peripheral surface of lthe felly band f, as shown particularly in Fig. 3.

The tire rim R, is held in position `upon the felly F, by the annular wedge-flanged side plates S, S, secured tothe felly by bolts d, d, passing through the felly within the inner line of the telly band f, said bolts d, cl, being locked in position by nuts d', d", in the usual way. These annular sideplates S, S, are each formed with an inwardly protruding peripheral Wedge flange s, for engageF ment with the annular inclined `marginal bearing surfaces 1', r, on the under side of the tire rim, as shown in Fig. 3, particularly. Obviously when secured in position ,c the annular Wedge-Hanged side plates S, S,

will effectually support the tire rim R, and sustain it against lateral strain or displacement, While by the removal of a single side plate S, the 'tire rim may be conveniently removed and replaced Without otherwise disturbing the parts.

By making the Wedge-flanges s, s, integral with the annular side plates S, S, the number of separate parts is reduced and their manipulation facilitated, so that the operation of removing Vo'r applying a tire rim R, is rendered simple, and economy in time and labor attained. Each side plate S, is necessarily split transversely, as at s, Fig. l, to facilitate the Wedging operation, and hence the bolt holes s2, are enlarged or elongated slightly to admit of the drawing together of the ends of the side plate.

That I claim as my invention and desire to secure by Letters Patent is,

1. The combination with awheel elly, of a tire rim in a single integral element formed on its under side with inclined annular marginal bearing surfaces and intermediate recesses and upon its opposite face with diagonal ribs, treads, cap plates embedded therein, bolts securing said cap plates in position, and nuts on said bolts disposed in said recesses.

2. The combination with a wheel telly, of a tire rim in a single integral element formed on its under side with inclined annular marginal bearing surfaces and intermediate recesses, and upon its opposite face with diagonal ribs, treads, cap plates embedded therein, bolts passing through saidribs and securing said cap plates in position, and nuts on said bolts and disposed in said recesses,

said ribs acting in conjunction with the treads and bolts -for the purpose set forth. JOHN J. PATTON. YVitnesses:
